To provide a sign detection device which is installed on a platform screen door device and detects a sign of failure of an electric motor that drives a scanning device that mechanically scans a sensor.SOLUTION: Sign detection units 20 and 30 is installed on a platform screen door device and detects a sign of failure of an electric motor that drives a scanning device that mechanically scans a sensor detecting the presence or absence of an obstruction. The sign detection units 20 and 30 have data collection units 21 and 31 for collecting data on control variables of a stepping motor 10 and a DC motor 11, data analysis units 22 and 32 for obtaining the number of pieces of data of control variables collected by the data collection units 21 and 31 that are out of a pre-set allowable range and alarm output units 23 and 33 for reporting that the number of pieces of data out of the allowable range obtained by the data analysis units 22 and 32 satisfies a pre-set condition, respectively.SELECTED DRAWING: Figure 3

    【課題】ホームドア装置に設置されて、センサを機械的にスキャン動作させるスキャン装置を駆動する電動機の故障の予兆を検出する。【解決手段】予兆検知部20、30は、ホームドア装置に設置されて、支障物の存否を検出するセンサを機械的にスキャン動作させるスキャン装置を駆動する電動機の故障の予兆を検知する。予兆検知部20,30は、ステッピングモータ10及びDCモータ11の制御変数のデータを収集するデータ収集部21,31と、データ収集部21,31で収集された制御変数のデータのうち、事前に設定された許容範囲から外れるデータの数を求めるデータ解析部22,32と、データ解析部22,32で求められた許容範囲から外れるデータの数が、事前に設定された条件を満たす場合に、その旨を報知する警報出力部23,33と、を有する。【選択図】図3
